Study summary

Compromised tissue oxygenation during surgery may negatively influence patient outcome. Primary cause of insufficient tissue oxygenation is reduced cardiac output due to hypovolemia and/or reduced cardiac contractility. In cardiac surgery patients especially, postoperative pericardia effusion and/or tamponade may further compromise cardiac function. Today, hemodynamically instable patients are often monitored by means of pulmonal artery catheters or transpulmonary thermodilution. However, these methods only allow quantification of functional limitations. Underlying causes may be investigated by relatively recent technology through hemodynamically focussed transesophageal echocardiography (ClariTEE(R) ImaCor) that also provide the possibility of continuous monitoring. It has been reported that a training program consisting of six hours may enable physicians who are unexperienced in the field of echocardiography to apply this new method. Up to now, there is no evidence whether this methods is associated with improved postoperative outcome.

Therefore we hypothesize that continuous hemodynamically focussed transesophageal echocardiography positively influences patient outcome (primary hypothesis). Furthermore, its application may decrease hospital expenses (secondary hypothesis).

What researchers measure

Primary outcomes

  1. Cumulative dosage of catecholamine application

    Time frame: three days beginning upon placement of device

Secondary outcomes

  1. degree and duration of other vasoactive substances

    i.e. epinephrine, levosimendan, dopamine, nitroglycerine, nitroprusside

    Time frame: degree and duration of other vasoactive substances three days beginning upon placement of device (or icu admission in control patients, respectively)

  2. fluid balance

    Time frame: day 1, 2 and 3, beginning upon placement of device (or icu admission in control patients, respectively)

  3. degree and duration of lactate acidosis

    maximum lactate level, date/time of maximum lactate level, first date/time when lactate \<20

    Time frame: degree and duration of other vasoactive substances three days beginning upon placement of device (or icu admission in control patients, respectively)

  4. duration of postoperative ventilation

    Time frame: first postoperative day until extubation (2 days on average)

  5. incidence of renal failure

    analysis of creatinine plasma level

    Time frame: three days beginning upon placement of device (or icu admission in control patients, respectively)

  6. incidence of hemodialysis

    Time frame: three days beginning upon placement of device (or icu admission in control patients, respectively)

  7. length of hospital stay

    Time frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks

  8. in-hospital mortality

    Time frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks

  9. cost of hospital stay

    Time frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks
